Alright kiddies, one more thought. It's small sample size, but I've noticed it in passing with other teams, so I've generated some data and you can test it out on your own. The patience, temper and makeup numbers are averages.
| Ovr difference | Avg age | Patience | Temper | Makeup |
| 9 | 23.00 | 54.50 | 32.50 | 73.50 |
| 8 | 23.00 | 32.50 | 23.00 | 65.00 |
| 6 | 21.50 | 60.00 | 62.67 | 57.67 |
| 5 | 22.00 | 57.89 | 47.56 | 58.11 |
| 4 | 22.00 | 57.69 | 44.85 | 60.54 |
| 3 | 23.40 | 62.20 | 31.00 | 75.80 |
| 2 | 23.54 | 28.38 | 58.77 | 60.38 |
| 1 | 24.80 | 34.20 | 54.30 | 55.05 |
| 0 | 26.88 | 38.03 | 60.82 | 60.97 |
The test is on the Whiny ******* in Happy Jack. OVR difference is comparing 86 games into current season with beginning of last season.
The 9 and 8 point differences only have 2 players in the sample size, so keep that in mind too.
Age is obvious. The younger you are, the more likely you are to develop.
I theorize that Makeup has a significant impact on how much you develop in short periods of time, and for how long. The 2nd highest average makeup got the largest development bump. The largest (3 OVR points) seems to overcome a higher average age to get a development bump anyway.
Of course there are other factors; promotion, demotion, playing time, inactive vs active etc etc. But I think it's still there.
